Patented sept. 1,1914;

To all whom it may concern;

residing at Ridgewood, New Jersey, and being a citizen of the United States, have in vented certain new and useful Improvements in Flush Car-Doors, of which the fol- -lowing is a full, clear, and exact description,

such as will enable others skilled in'- the art to which it appertains to make and to use the same, referencebeing had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modiications thereof will occur to persons skilled in the art.

. by the device.- Fig. 4 is an enlarged detailed section taken on the line 4-4 of Fig. 1 and showing the principal parts of the invention. Fig. 5 1s a detailed section taken on the llne 5-5 of Fig. 3, but on the same scale as shown in Fig. 4. Fig. 6 shows the device somewhat modified so as to enable the operating shaft to be placed directly under the floor f the car, projecting beyond it, as it does in Fig. 3. FlgS. 17, 8, forms of the invention.

The object of this invention is to provide a simple, effective and an easily operated mechanism for locking'and releasing dumpcar doors of the drop bottom type.

The invention will behereinafter fully -described and claimed with reference to the accompanying three sheets of drawingsl Referring to the parts by numerals, 1 1s an underframe of a gondola car, composed of theusu'al'body holsters 2, carrying center where necessary, instead ofl and 9 show details of modified sills-3, to which are fastened 'cross-bearers 4. Be 1t known that I, LEOPOLD ALMQUIST,

rSupported on the under'frame are 'posts 5, to wwhich the side walls 6 are riveted. Wind:- mg-shafts 7, two in number, one located on each side of the car, are supported in brackets (a riveted to the body bolstersand crossbearers, -as shown ill-*dotted lines in Figs. 2 and 3. he shafts 7 carry drums-8 for winding chains 9, which are fastened to doors 10. `through brackets 11, depending therefrom for the purpose of voperating the same. The doors -lO are hinged on pins 12 carried in brackets 13, as shown in Figs. 2 and 3,- and -the outer ends of the said doors when closed, impinge Hoor angles 14, which are riveted to theside walls 6.

Each winding-shaft i by a lever 7 b, pivotally mounted thereon, and' carrying a pawl 7 which engages a. ratchet 7d, fixed on the said-shaft, and is locked by a pawl 7e, carried on a bracket 7*, which is fastened to the-underframe in the ordinary way. Each lever 7b is heldin position vby a ring Tg, whichpencircles the upper end'of the former, and is-slidable in a vertical openingv formed in a bracketi'h, which is riveted to the sidewall 6.- 'On each side of the car is a shaft 15, which operates all of the latches thereon simultaneously, and turns inl suitable ope ings formed in the posts 5 and an- Keyedon the shaft 15, or otherwise suitably fastened thereto, are circularcains, or eccentrics 17, whichl are mounted to-turncintcorl'- roller 21, which is carried on a pin 22. The latter issupported in brackets 23, firmly riv- -eted to the floor' angle 14 at one end, and. to the depending angles 16 atthefother.' The It will be noted that the door-lifting and i feo' operates alll the 'i doors on one side of the car', and is operated gles 16,-depending from the side walls 6.

'responding openings 18,`fo.rmed in latches v or levers 19. Each of the latter has an in-4V V ,clined slot 20, formed therein, to receive a .ends of the cam 17 bear pin is held in place by split pins 2l, engaging into holes in the endsthereof. The y against the angles 16, as shown in Fig. l, to regulate the end motion of the former, and thelatch 19 is heldV centrally on the said cam, by a set-screwY 25,- passing through the latter, and the pivot point of said set screw engages into an annular groove Q6, formed therein, as shown in vl" ig. 5, thereby preventing the sides of the latch 19 from' rolling against the surfaces 0f` the brackets 23 adjacent thereto, thus eliminating friction between the said latter parts. Each end of the shaft 15 is squared for the reception of a lever 27, for controlling the locking mechanism. 'in its upright or locked position against the side of the car, by a ring :28, encircling the upper end of the former and movable in a vertical opening formed by a strap 29, similar to 7h, which is the common contrivance now in use on dump cars. rlhe strap 29 is vriveted to the side Wall 6.

The operation for dumping the load is as ollowsz-The rings 7 g are raised, the levers successively moved out of engagement with alle ratchet-s 7 d, leaving the Winding-shaft 7 free to turn. The rings 28 are then lifted and the levers 27 moved out, shaft 15 a fractional turn, causing the eccentrics 17 to partly revolve about the center of the said shaftA and impart motion to the latches 19, Which cause the latter to ride on the rollers 2l, in the inclined slots 20, and recede from the doors 10, to the lowest dotted position shown in Fig. 3, thereby releasing the latter, which drop open under the Weight of the load in the car and, in their descent, unwind the chains 9 from the drums 8 and dump the load.

'After the car has been emptied, the wind-v ing-shaft 7 is rotated by the lever 7 b through .the ratchet 7d, and paivl 7C, Winding the chain 9 on the drums 8 and lifting the doors l0 to the dotted position shown in F ig. 3, Where they are ready to be engaged by the latches 19. The levers 27 are then `moved to their upright position, rotating` the shaft 15 inthe reverse direction .to that just described, this causing the eecentrics or cams 17 to bear inward and down on the outer ends of the latches 19, forcing the inner ends of the latter to ride up on the rollers 2l in the inclined slots 20, giving a lifting motioIl t0 the said latches, in addition to that produced by the eccentricity of the cams 17, acting -on the said latches or levers 19, which are fulcrumed on the pins In this last movement of the latches 19 the shoulders 19a thereof will strike the depending flanges 101 of the doors and, as the inner ends of the latches rise, said doors will be carried on said shoulders to their final closed position,

The lever 27 is held swung out and the paWls 7e and 7c are giving thel The latter operation brings the doors 10 to a closed and locked position, impinging the angle 11i, asshoivn in full lines in Fig. 3, and the rings Share then lowered on the upper ends of the levers 27, as shown in lfig. l, to prevent then-'being jarred loose.

There are manifest advantages in operating the locking means from an auxiliary shaft not used'to receive the weight of the doors in the ordinary operation of closing, as such auxiliary shaft is less liable to distortion when used primarily for controlling the locking means.

In both forms of the invention, it is evident that if the shaft 15 is continued beyond the end Wall of the car said shaft may be provided with any suitable means for 1n which case such means may comprise the lever 2T or its equivalent with suitable holding means therefor.
